SHOE.

Application filed September 6, 1917.

To all whom it may concern:

Be it known that I, GEORGE E. anners, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain improvements in Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of shoes and particularly to improvements in shoe soles by means of which a sole can be maintained in place on a last bottom during the operations of applying a shoe upper to the last and securing the upper to the sole. By way of illustration, the invention is herein shown as embodied in an insole of the type used in the manufacture oi a welt shoe but it is apparent that the invention is .also applicable to the manufacture of shoes of other types.

It is the present practice in the manutacture of shoes of 'arious types to tack the insoles to the bottoms of the lasts and after the shoe uppers have been secured to the insoles to rnnove the insole fastening tacks. The tacks are necessarily located inside the marginal area of the insole that is covered by the ovcrlasted upper and, therefore, do not hold the edge of the insole closely to the edge of the last. in such subsequent operations on the shoe as the pulling-over operation, and sometimes the lasting operation, this presents such a serious diiiiculty that special attachments are commonly provided on the machines which perform these operations to supplement the insole fastening tacks. Moreover the tacks are diiiicult to remove and a tack is sometimes left, or its point is broken oil, so that a part of the tack remains in the insole where it injures the foot of the wearer. Objects o'f the present invention are to provide an improved sole the use of which will enable a more efficient attachment of the sole to the bottom of the last for the succeeding shoe upper shaping and securing operations than is practical with the tacks heretotore employed; to dlspense with tacks or the like Specification of Letters Patent.

fastenings such as those above named, thereby economizing in the labor cost incident to the use or" tacks; and, furthermore, to eliminate the liability of injury from tacks or parts of tacks remaining in the finished shoe.

An important feature of this invention consists in a sole having means for holding its marginal edge to a last, such as a member or members adapted to extend beyond its periphery and be engaged with the last to secure the insole in position on the last. In the illustrated embodiment of the invention an insole is provided with a plurality of adhesive coated members extended therefrom in position to attach to the sides of the last and of suitable strength to hold the insole while the shoe upper is being applied and secured but to be broken readily by the operation of pulling the last from the shoe.

These and other features of the invention will more fully appear from the following description read in connection with the accompanying drawings of an illustrative embodiment of the invention, and will then be particularly pointed out in the claims. 7

Figure l of the drawings is a perspective view of an insole illustrating a preferred embodiment of the invention.

Fig. 2 is a perspective view illustrating the use of the insole shown in Fig. 1.

in the drawings, 2 represents an insole of the type employed in the mamrfacture of welt shoes, and as shown it consists of a laminated structure having a sewing rib l formed upon its upper surface. In accordance with this invention, the insole is pro vided with means for securing it in position on the last 6 during the succeeding operations on the shoe. In the illustrated embodiment of the invention, these means comprise a plurality of tabs 8 located at selected points about the periphery of the insole 2 and adapted to be attached to the sides of the last 6 to hold the insole against displace ment on the last bottom and maintain its edge against the edge of the last. The tabs 8 are preferably narrow strips of paper one end of each of which is secured between the laminated sheets comprising the insole with a portion projecting beyond the edge or" the insole and having its lower surface provided with an adhesive coating which enables the tab to adhere to the side of the last thereby holding the insole in proper position on the last. Preferably thetabs S are made of a paper which is of suitable strength to be readily torn when the operation of pulling the last from the shoe is performed so as to free the insole from the last. In order to hold the insole 2 upon the last 6 in the most advantageous manner, the tabs are located preferably; at the toe, the tip line, the ball line and at either side of the breast line of the shoe, as illustrated. In commercial use of this invention, the insoles may conveniently be made in the ordinary manner wlth the tabs anchored between the two lamina of the insoles as above described, the projecting portlons of the tabs 8 be ng folded over on to the upper surface of the lnsoles as indicated in full lines in Fig. 1 of the drawings so that no inconvenience results in handling the insoles because of the pressure of the tabs.

'firmly held in position against the edge of the last whereby the pulling-over operation and the lasting operation may be performed upon the shoe without liability of themargin of the insole being raised out of position on the last bottom during these operations and the necessity of employing special attachments on the pulling-over and lasting machines to overcome this difficulty is eliminated. When the last is withdrawn from the shoe, the tab conneections between the insole 2 and the last 6 are torn and the last readily withdrawn, the tabs 8 showing no llldlcit tion in the interior of the shoe.

which have been heretofore experienced with the use of the tacks forholding the insole in position on the last, for'example, breaking the tacks in withdrawing them fromthe insole and the consequent liability of the tack remaining in the shoe and injuring the wearers foot are eliminated and the defacement of the last by the numerous tack holes, and a better holding of the insole is obtained for the pulling-over and lasting operations.

It will thus be seen that the disadvanta es are avoided Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is

'1. As an article of manufacture, a sole having members adapted to extend beyond its periphery and be engagedwithalast to secure the sole in position on thela-st.

2. As an article of manufacture, a sole having means for holding its marginal edge to a last.

3. As an article of manufacture, a sole having means for connecting its marginal edge at a plurality of points to a last.

4.= As an article of manufacture, an insole having a plurality of members located at selected points on the periphery and adapted to be engaged with a face of a last to hold the insole in assembled relation to the last bottom.

5. As an article of manufacture, a sole having a plurality of flexible members adapted to be adhesively engaged with the side faces of the last to hold the sole in positlon on the last bottom durmg the opera tions of applying and securing the shoe upper.

'i LS an article of manufacturaan insole having an adhesive coated paper strip extending into'position' to be stuck to the last and of suitablestrength to hold the insole while the shoe upper isbeing applied and secured and to be broken by the operation of pulling the last from the shoe.

7. As an article of manufacture,a composite insole having a portion of an" adhesive strip secured between the plies of the insole and another portion arranged to be attached to a last for holding. the "insole on the last bottom.

8. As an article of manufacture, an insole having a sewing rib and a feather and an adhesive coated member extending from the feather and adapted to be stuck to the last to hold the insole on "the last bottom during the application ofthe upper and its connection to the sewing rib and to be broken by the withdrawal of the last from the shoe.

9. As an article of manufacture, an insole provided with a sewing rib and having a feather and means for connectingthe said feather of the insole to a. last.

10. esan article'of manufacture, an insole having a sewing rib and a feather and a plurality of adhesive members arranged to hold the feather to the last at spaced points along the forepart and shank. I

i In testimony whereof I have signed my name to this specification.
